Android快速開發之——最常用的基本列表框架搭建
阿新 • • 發佈：2019-02-06
框架基本介紹:
這是一個基本的列表頁面的開發框架，這個列表頁面的功能有:可自由配置標題欄、下拉重新整理、上拉載入、網路請求時展示等待動畫、請求失敗及資料為空的頁面展示。
寫在前面：
本文可以自由的進行網路請求框架、圖片載入框架、上拉重新整理下拉載入框架、載入等待動效框架的自由配置。配置鴻洋大神的萬能的ListView的介面卡框架。
這樣一個完整功能的列表頁面，你們需要多少程式碼？
private List<BeanMyTask> datas;
private CommeAdapter<BeanMyTask> adapter;
@Override 這麼些程式碼就能直接完成這樣的一個完成的頁面的開發。而且類似功能的程式碼只需要繼承基類，做一個json資料解析，建立列表介面卡。
我的無敵基類。
